ADVERTISING-CLOCK.

SPECIFICATION forming part of Letters Patent No. 385,430, dated July 3, 1888.

Application tiled February 9.9, 18H8. Serial N0.2G:',70:'. (No mu`:cl.l

This invention relates to certainv new and useful improvements in advertising clocks, and is designed as an improvement upon the construction shown in my patent, No. 345,739, dated July 20, ISSG, and the novelty residesin the pecularitics of construction and the combinatious, arrangement, and adaptation of parts, all as more fully hereinafter described, shown in the drawing, and then particularly pointed ont in the claims.

The invention is clearly illustrated in the accompanying drawing, which represents a front elevation of a clock provided with my improved advertising attachment, with parts broken away and parts in section in-order to betterlshow the construction.

In the accompanying drawing, A represents a clock, of any suitable design, provided with the usual pendulum, c, and at its bottom or lower end a casing, B, formed with openings b, with glass fronts, through which to see the advertisements on the revolving cylinders, the number of openingsv corresponding with the number of cylinders used. I have shown in the present instance three revolving cylinders, G D E, and when more than one are used eogs c are employed, which extend around the circumference of each cylinder at the lower end thereof, the cogs'on one cylinder engaging with those on the other, thus motion from the master-cylinder being communicated to the others, as shown.

The shafts ofthe cylinders have their bearings in the top and bottom of' the casings B, the shaft of the master-cylinder extending above the top of the casing and carrying a cogwheel, d. This cog-wheel meshes with the teeth of the wheel c, and on the shaft of said wheel is a pinion, f, with which engages a large cog-wheel, g, suitablykeyed to a post, h,

for winding the gearing, said wheel havingr the usual pawl-and-ratchet wheel and spring, t', connected tothe post.

F is a cam or ratchet wheel secured to the post of the clock and provided with the camlceth, as shown.

rIhe mechanism above described is similar to that shown and described in my former patent; but I do not restrict myself to such particular arrangement of gearing, as other forms may be found preferable or desirable for giving motion to the cylinders.

The cylinders are preferably, though not necessarily, like those described in my former patent, and are provided with curved slots for inserting the advertisingcards, which are rctained in place by vertical strips Z, overlap- -piug thev vertical edges of the cards, and the strips m, secured around the top and bottom of the cylinders.

After the driving mechanism is wound up to impart motion to the cylinders, such motion iscontrolled by mechanism attached to the cloclework, so that the movement of the cylinders will be intermittent,or ati ntervals, and

the extent of movement such as to enable one card only on cach cylinder to bc exposed to view. In the present instance this mechanism is as follows: G is a lever pivoted at one end, as at G', and at the other hooked or pointed, as at a. To this lever, near thehooked end, is connected one end of the rod I-I, thc opposite end of which is connected to the lever I to one side of its pivot-pointt". Thislever I carries two pins, .I K,- which are of sutllcient lengt-h to extend down through andinto the casing E, between the radial spokes L of the central cylinder. As the wheel-F is moved around in the direction of the arrow, the pointed end of the lever G will be elevated, and when tlie point of thev lever has about reached the point n: on the tooth of the wheel the pin K will be raised clear of the spoke of the cylinder, withwhich itis now shown enga-ged orin t'rontof, allowing the said cylinder to turn; but as soon as the pin K is raised clear of the spokes the pin Jfalls and drops in front of a spoke on its sideofthe cylinder; but the moment the pointed endV of the lever G rides over the point :o and falls into the next notch the end of the lever Learrying the pin K,is depressed, and. the pin IOO ing.

shown; but this, however, may be changedby increasing or decreasing the number and size ofthe teeth of the wheel,according to the time Uthe lever I.

desired between each movement of the cylinders.

M is a bell located within the clock-case,and 'N isthe hammer carried by the outer end of As the lever drops, the hammer falls and strikes the bell before the cylinders begin to move, and calls -attention to the fact that new advertising cards are about toA be' brought in view.

The attachment is cheap and simple, not easy .to get out of order, and may 'be applied to clocks at a triding expense.

l. The combination, with the clock andthe upright and horizontally-revolving cylinders,

` one of which is-provided at its upper end with radial spokes, of the intermediate lever, vertical holding-rods carried by said lever` and operating between the spokes, and a rod connected to said lever and operatedby mechanism on the post of the clock, substantially as and for the purpose speeilied.l

2. -The combination, with the clock and the revolving cylinders, one of which is provided with radial spokes at its upper end, of a holding and releasing mechanism operated by the clock-.Worksand consisting of a cam-wheel on the post of the clock, the intermediate pivoted lever, I, the rod H, actuated by said camwheel and connected with said lever, and the pins earriedby said lever and extending down between said spokes,substantially as described. t '3. The combination, with the clock andthe revolving'cylindersfone of which isprovided 'near itsv upper end with radial spokes, .of a

holding and releasing mechanism operated by the elock-works,and consisting of a cam-wheel on the post of the clock, the pivoted lever G,

' the intermediate pivoted lever, I, the rod conf necting said levers, and the downwardly-projecting pins carried by the intermediate lever and extending between the spokes, s ubstan, tially asl and forthe purpose specied.

4. The'combination, with the'clock'and the revolving cylinders, one of which is provided near its upper end with radial spokes, of a' holding and releasing mechanism operated by -the clock-works,and consisting of a cam-Wheel4 ou the post of the clock, the pivoted lever G, the intermediate pivoted lever, I, the rod connectingsaidlevers,thedownwardly-projectingpins carried by the intermediate lever and extending between the spokes, the bell, and the bellhammer carried by said intermediate lever, substantially as described.

' In testimony that l'. claim the above I have hereunto subscribed my name in the presence of two witnesses.
